Code that breaks for me:
import direct.directbase.DirectStart
model = loader.loadModel("data/units/sword/sword.bam")
i had the same problem on win 7 64, but dont remember whats wrong and how i fixed
try converting to egg
i get this when trieng to convert
Loading sword.bam
:util:bam(error): Bam file is version 6.22.
:util:bam(error): This program can only load version 6.14 through 6.19 bams.
:loader(error): Couldn't load file sword.bam: invalid.
Unable to load sword.bam
I though this will go away after I installed the most recent version of ubuntu 9.10 64 bit from the nightly builder: But it looks like its still there as my unit tests say:

Yes I saw you committing it on irc. I tried to figure it out myself but that was a bit hard. I compiled panda3d without threads and that worked. Now I need to get your fix and compile with threads.
I am trying to use packp3d.p3d and it deadlocks too!

You’d have to host your own runtime somewhere, and build it with the URL to that address; and then you’d have to use the packp3d that was built with that URL.
